Rock and gem shows aren't just a bunch of long-haired hippies waving crystals, or grizzled miners with chunks of stones falling out of their pockets. There are many types of items for sale at these events from precious gems in intricate jewelry settings to raw stones in every variety imaginable.
I won a Himalayan salt crystal lamp donated by Book and Bead Outlet, but since I already have one, they were kind enough to let me exchange it for a copper and freshwater pearl bracelet. Though it was a little more than I should have spent, I couldn't resist the heart-shaped amethyst stone. The cactus crystal? It's so phallic, I had to have it!
If you get the opportunity, go to a show in your area. You never know what you will find amongst the rocks.
